Benefits of technology

The solution enables safer and more efficient blade exchange on dermatomes by providing a secure mechanism for alignment and handling, reducing the risk of injury and facilitating the process with a magnetic tool for easy blade management.

Problems solved by technology

Removing and installing blades presents significant hazards to health care workers performing or assisting with such procedures.
Because the blade is securely held on the instrument, removing and installing blades may be difficult and the health care worker may be seriously cut by the exposed blade.

Embodiment Construction

[0018]A blade exchange device may be used to remove and / or install a blade on a medical or surgical instrument such as a dermatome. The blade exchange device generally includes a base portion and a blade engaging portion that engages the blade being removed or installed. The blade exchange device may be used in a system that also includes a magnetic tool for coupling and moving the blades that are removed or installed. The blade exchange device, system and method may be used, for example, with commercially available dermatome instruments such as the type known as the Goulian-Weck knife.

[0019]Referring to FIGS. 1A-1D, one embodiment of a blade exchange device 100 includes a base portion 110 and a blade engaging portion 120 extending from the base portion 110 to engage a blade 102. In this embodiment, the blade engaging portion 120 extends from one end of the base portion 110. The blade engaging portion 120 includes one or more blade locating protrusions, such as pins 122, configured ...

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Patent Application Ser. No. 61 / 315,883 filed on Mar. 19, 2010, which is fully incorporated herein by reference.TECHNICAL FIELD[0002]The present invention relates to removing and installing blades on surgical or medical instruments.BACKGROUND INFORMATION[0003]Surgical or medical instruments often use sharp razor blades. One such instrument is known as a dermatome and is used to produce thin slices of skin from a donor area in order to make skin grafts, for example, to reconstitute skin areas damaged by burns or other trauma. A conventional dermatome generally includes a handle that securely holds the blade and allows manipulation of the blade during use. One example of a dermatome is known as a Goulian-Weck knife. In this type of a dermatome, the handle removably secures the blade by friction and a guard is located over the blade to guard the blade edge and allow a certain thic...
